Abstract: The present disclosure provides a cryo-electron microscopy image processing method and apparatus, a terminal, and a storage medium. The cryo-electron microscopy image processing method includes: obtaining a cryo-electron microscopy image; encoding the cryo-electron microscopy image into latent variables through an encoder; converting the latent variables into an atomic model structure through a decoder; correcting the atomic model structure using a loss function to obtain a corrected atomic model structure, where the loss function includes a bond length constraint loss function, a clash constraint loss function, and a spring constraint loss function; and converting, through a projector module, the corrected atomic model structure into a density map represented by Gaussian spheres, and projecting the density map to obtain a projection image.

Abstract: Implementations of the present disclosure relate to methods, devices, and computer program products of extracting a feature for multimedia data that comprises a plurality of medium types. In a method, a first feature is determined for a first medium type in the plurality of medium types by masking a portion in a first medium object with the first medium type. A second feature is determined for a second medium type other than the first medium type in the plurality of medium types. The feature is generated for the multimedia data based on the first and second features. With these implementations, multiple medium types are considered in the feature extraction, and thus the feature may fully reflect various aspects of the multimedia data in an accurate way.

Abstract: The present disclosure provides an expression driving method and apparatus, and a training method and apparatus of an expression driving model. The expression driving method includes acquiring a first video; and inputting the first video into a pre-trained expression driving model to obtain a second video. The expression driving model is trained based on a target sample image and a plurality of first sample images. A facial image in the second video is generated based on the target sample image. A gesture expression feature of the facial image in the second video is the same as a gesture expression feature of a facial image in the first video.
